Reading Ekko's Reveal.

One paragraph in and it does not look good.

We’re about to send League’s next champion out to PBE! Ekko’s a powerful skirmishing assassin who thrives in extended fights, using his mobility and crowd control to slow and stun enemies as he whittles down his targets. And if he starts to lose a fight, the brilliant boy from Zaun can rewind time a little and try again.

When the words "Assassin, thrives in extended fights, mobility, crowd control, stun" are used to describe a champion, it makes me nervous.

Edit Passive:

Passive: Z-Drive Resonance

Ekko's damaging spells and attacks build up Resonance stacks on his enemies. Every third attack against the same target triggers Ekko’s passive, dealing bonus damage and slowing his enemy. If he triggers his passive on an enemy champion, Ekko also gains a strong movement speed buff.

If was just the damage and MS, then I think it'd be fine, but with the slow, I think it will be flat out too much. Good luck trying to fight him as an immobile melee.

Edit Q:

Q: Timewinder

Ekko throws a device in a target direction, damaging all enemies along its path. Once it reaches max distance or hits an enemy champion, the device expands, creating a field that slows all enemy and neutral units. After a moment, the device contracts and rushes back to Ekko, dealing extra damage to all enemies in its path.

Again, good luck trying to fight him as an immobile melee. It's okay though, I was sort of over playing Garen/Sion/Nunu/etc.

Edit W:

W: Parallel Convergence

Passive: Ekko’s basic attacks deal bonus damage to low health targets. Active: Ekko opens a time rift, creating an alternate reality copy of him that tosses a device to a target location. After a delay, the device expands into a broad slowing zone. If Ekko enters the sphere, it detonates, granting him a shield while stunning all enemies inside.

So essentially, I don't really get any choice in the matter if I fight him as a melee?

Edit E:

E: Phase Dive

Ekko dashes a fixed distance towards a target area. Once his initial dash has ended, Ekko gains greatly increased range on his next basic attack, and blinks to his target to deal damage and apply on-hit and spell effects.

Thanks for answering that so fast Riot.

Edit R:

R: Chronobreak

Ekko rewinds time, briefly turning untargetable and invulnerable before reappearing wherever he was a few seconds ago. Once he reappears, Ekko recovers a portion of the health he lost over those few seconds while dealing tons of damage to all nearby enemies.

...

Edit Final Thoughts: I haven't seen his mana costs, cds, or his scalings yet, but he seems like the love child of Azir and Poppy.
